DIAL FOR RECORDING APPARATUS.

SPECIFICATION forming part of Letters atent No. 573,606, dated December 22, 1896.

Application tiled March 4,1896. Serial No. 581,822. (No model.)

.T0 @ZZ whom it' may concern:

Be it known that I, FREDERICK G. LoUeEn, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain newand useful Improvements in Dials for Recording Apparatus; and I do hereby declare the following to be a full, clear7 and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to watchmens clocks7 or watches, so called-that is, clocks or watches provided with mechanism arranged to register or record on removable dials or sheets the time at which a watchman in making his rounds visits the several stations or rooms of a factory or plant guarded by him. The present invention, however, relates more particularly to a novel record sheet or dial capable of being used onclocks or watches of the class just referred to.

In certain types of time-registering apparatus the suitably-printed dials or sheet-disks on which the watchmans record is made has to be changed daily. Obviously in such cases a continuous record cannot be secured-that is, a record covering a number or series of days in succession-owing to the fact that single disks or dials are employed.

I am aware that it has been proposed to provide time-registering apparatus with means whereby a great number of individual recording-sheets may be introduced and delivered automatically an d singly at stated intervalsas, for instance, at the end of each day-said delivered sheet bearing the recording-mark or record.

The object I have in view is to produce a record-disk or continuous multiple dial capable of being used in lieu of the usual wellknown single sheet dial and also without change in the clock or watch mechanism.

To that end my invention consists, essentially, of a plurality of suitably-printed superimposed single disks joined together so as to form a continuous spiral or helix and capable of being removably secured to the clock or actuating mechanism.

In the accompanying drawing the figure is a perspective View of my improved multiple or continuous spiral dial for recording apparatus, the convolutions of the dial being separated so as to represent the article more clearly.

I may state here that practically any type or class of recording clocks or watches, or even other recording devices employing flat disks or record-sheets, may be readily adapted to use my improved dial. In fact, the latter may be substituted for the single disk without any change whatever in the mechanism. It is equally well adapted to be used on pendulum, electric, or spring-actuated time apparatus.

The usual dial is simply a single disk having its surface divided into a series of twelve divisions, which in turn are subdivided into any desired number of parts, the center of the dial being adapted to receive the clockspindle.

My improved record-dial consists of a number of single disks joined together to form a continuous spiral or helix u. As drawn, the disks are cut or slitted radially alike at any desired point in the disks surface, said slits extendinginwardly from the periphery. The disks are united together .at said severed points, the edge or end of -the upper disk abutting against the adjacent edge of the next lower disk, the parts being secured together by a strip of adhesive paper 19 or in any other suitable manner, thus forming a smooth joint a2.. The entire number of disks of the series are similarly joined, thereby forming the contin nous spiral a, as shown in the figure, though said iigure represen ts the several coils or members separated to an exaggerated extentin order to more clearly illustrate the construction of the dial.

Thev manner of affixing or securing my improved dial to the clock is substantially the same as heretofore practiced.

I do not limit the use of my improved mul tiple dial solely to this class of time-recording apparatus, as it may be used on other types of recording devices employing single-disk dials without departing from the spirit of the invention, thereby rendering such devices capable of producing continuous records upon the dials.

ICO

I un well ztwztre that recordingI devices have hitherto been. .provided with Continuous lztt strips or webs of paper, which are mecha-nienlly wound upon secondary rolls or barrels eoneurrentiywth the not of producing :t reeord upon them. Therefore I do not claim sueh construction broadly.

I eiztiln as new and desire to secure by i United States Letters Pntentt The record sheet or dial hereinbefore described, the same consisting` ol? a series of suitable superposed disks at joined together und 'forming a continuous spiriti or helix, und having the top and bottom disks thereof out so as to 'form free ends, for the purpose spoot 15 fied.

In testimony whereof I have affixed n1 y si nature 'in presence of two witnesses.
